Abstract: The present invention concerns a hand holdable writing tool for generating a visual representation on a writable-erasable, passive medium. The invention also provides the assembly of the writing tool and the medium. The writing tool comprises a sensor capable of sensing non-visible light, and a data processing entity, configured for activating and/or disactivating individual inducer entities of the tool, thereby inducing image elements of the medium to generate said visual representation.

Abstract: A modular building structure has a framework including a plurality of rods and connectors to interconnect the plurality of rods together, and empty spaces bordered by corresponding rods. A plurality of panels, wherein one panel is mounted inside each empty space and connected to the framework to create an interior, an air chamber layer inside which air may circulate. The air chamber layer forms at least a portion of an outer surface of the interior. At least one upper valve system is mounted in the upper portion of the structure, and at least one lower valve system is mounted in the lower portion of the structure. The upper and lower valve systems are selectively operable to regulate the thermal conditions inside the interior as a function of the meteorological conditions outside and a desired temperature inside. A method operates the upper and lower valve systems.

Abstract: The present invention concerns an electronic device, preferably a thin film electronic device, and a method for producing the device. The device comprises an intermediate structure (301, 401, 501) at the interface between neighboring unit devices connected in series. The intermediate structure is suitable to employ deposition techniques that make it possible to avoid steps of scribing or patterning insulating and/or separating lines between adjacent layers of the device.

Abstract: The invention relates to an optical stylus (10) for an optical position determination device (1) comprising a position-encoded surface (50) having different position-encoding patterns (52). The optical stylus (10) comprises a housing (12) including: an image sensor (20) for capturing at least one image of any position-encoding pattern (52) of the position-encoded surface (50): an optical arrangement (15) comprising a dynamic optical element (16) configured to be electrically actuated in order to adjust the focal length of the optical stylus (10) as a function of a separation distance (D) between a reference point of the optical stylus (10) and the position of any position-encoding pattern (52) to have a substantially in-focus position-encoding pattern (52) corresponding to the position of the optical stylus (10), and a control unit (24) to control the dynamical optical element (16). The optical stylus further comprises a distance measurement sensor (32) to measure the separation distance (D).
